The guy on Auto Auction Rebuilds used it on an engine that had a stuck valve, and it seemed to work.

My favorite use for MMO was to lube my pneumatic air tools. I had a little squeeze bottle and would periodically shoot a squirt into the air inlet nipple. Upon first use, it blew out in a fine mist but it kept the air guns working fine for years and years.

Gasoline additive. Or for adding to oil before a change.

I even have an oiler unit for it on my Valiant

That would come in handy in case a big truck starts chasing you.

It is like spirits for your car. A little does no harm and may loosen a bit of carbon. A lot causes your car to sway and trip like a wineo.


make the inside of your engine oil cap white.
don't use.

I use MMO in my gas and I may use a shot (4oz per qt) in the crankcase to dissolve gum that causes your rotating assembly to drag, its a great solvent and harmless if used properly. Just remember if adding to the sump, it drops the viscosity about 1 point (from 11 to 10). In my experience, running MMO for at least 2K has some real positive results in the sump and your fuel economy shows some improvement.. Its also a tank stabilizer in diesel or home heating fuel with the ability to clean the furnace burner.

I mixed it in fuel and oil to free up lifters in a ford mod motor that set up for a few years.
